Depends. Where is the drain line and the supply lines in relation to where you want the washer? If there is easy access to them, it wouldn't be too much. The dryer has to have a vent and this should not be too long or go around corners. The dryer also must have an 240 VAC electrical outlet and, like the plumbing, if the 240 electrical circuit is easy to reach, you would not be in too deep there either. Not knowing you layout, it's pretty hard to get very specific.
